v
Make
sure
that
you
are
using
the
correct
device
drivers,
which
are
supplied
with
your
server.
v
Check
for
operating-system-specific
causes
for
the
problem.
v
Make
sure
that
the
device
drivers
on
the
client
and
server
are
using
the
same
protocol.
v
Test
the
Ethernet
controller.
The
way
the
Ethernet
controller
is
tested
depends
on
which
operating
system
you
are
using
(see
the

problem
FRU/actions
The
server
stops
running
when
loading
device
drivers.
The
PCI
BIOS
interrupt
settings
are
incorrect.
Check
the
following:
v
Determine
if
the
interrupt
(IRQ)
setting
assigned
to
the
Ethernet
controller
is
also
assigned
to
another
device
in
the
Configuration/Setup
Utility
program.
Although
interrupt
sharing
is
allowed
for
PCI
devices,
some
devices
do
not
function
well
when
they
share
an
interrupt
with
a
dissimilar
PCI
device.
Try
changing
the
IRQ
assigned
to
the
Ethernet
controller
or
the
other
device.
For
example,
for
NetWare
Versions
3
and
4,
it
is
recommended
that
disk
controllers
not
share
interrupts
with
LAN
controllers.
v
Make
sure
that
you
are
using
the
most
recent
device
driver
available
from
the
World
Wide
Web.
v
Reseat
or
replace
the
adapter.

Check
the

v
Make
sure
that
the
hub
is
turned
on.
v
Check
all
connections
at
the
Ethernet
controller
and
the
hub.
v
Use
another
port
on
the
hub.
v
If
the
hub
does
not
support
auto-negotiation,
manually
configure
the
Ethernet
controller
to
match
the
hub.
v
If
you
manually
configured
the

make
sure
that
you
also
manually
configure
the

v
Reseat
or
replace
the

Check
the

v
Make
sure
that
you
have
loaded
the

v
The

be
idle.
Try
sending
data
from

Check
the
following:
v
Make
sure
that
you
are
using
Category
5
or
higher
cabling
when
operating
the

at
100
